Looks great! The story is easy to follow, and the pacing is good. When I get to the bottom of the page, I want to see what happens next, so that’s all good.
My critique is not entirely legit, as I am only seeing a few pages, but I thought it while reading it, so I’ll say it.
Some of the captions are fine, but some can be said in less words. Also, all of the captions (well, almost all of them,) are referring to exactly what he is doing at that moment. Since they are his thoughts, and thoughts wander, you can use them to give us a wider scope of who he is as a character. If I were in his shoes, I would be thinking of family, hope I make it back because the new Star Wars is in three days, etc.
With four pages, it moves quickly and is a fun read, but ultimately, it is the character that will keep us attached/reading. Again, not a legit critique, because I was interested the whole time. Just thinking if it continued that way…
